<p><font face="Helvetica, Arial, sans-serif">Greetings,</font></p>
<p><font face="Helvetica, Arial, sans-serif">We are running DB
cluster for our web applications and want to switch back-end
connection from one DB to another in case of failure. The
application connects with DB using DNS host names. We want to do
application health check for our Database and do DNS record
changes based on health check (like ifurlup). Anybody has
implemented any such scenario using LUA scripting or something
else.</font><br>
